arm-autonomy/xen-devicetree: change Xen dts and n1sdp dtsi

Browse Source 
The current Xen dts produced by the layer is using an old
way to specify the dom0 kernel module that won't be supported
anymore in Xen 4.16 when booting through UEFI.

Change xen.dtsi.in to have the Dom0 kernel module as a
direct child of /chosen node.

For the n1sdp, Grub2 is responsible to create the Dom0
kernel node and properly setup the #address-cells and
the #size-cells properties, so modify the dynamic layer
dtsi for n1sdp to remove these node and properties from
the yocto generated dtb for Xen.
